Bluebottle jellyfish sting

Bluebottles are recognized by their characteristic blue translucent appearance and are the leading cause of jellyfish stings in the world. The sting is immediately painful and leaves a distinctive ribbon-like sting across the skin. The sting is caused by venom darts lining the tentacles that deploy on contact. Depending on the site affected, the stings can be very painful, but this will usually fade within an hour or two. The sting eruption can last for a few days. Bluebottle stings are not contagious and can't be passed on to others.

Start with rinsing the sting in seawater and ensuring all tentacles are removed. Next, put the affected skin in warm water, about 110 degrees F, for 20 minutes. This serves to partially break down the toxin and dilutes the intensity of pain from the sting. Applying an ice pack is an alternative. Although there is some suggestion that the application of vinegar may be useful for box jellyfish stings, it's not helpful with bluebottle stings and may even worsen the pain.

It is best to seek medical attention if you experience any symptoms of a wider generalized reaction to the sting. Symptoms such as vomiting, sweating, palpations, swelling, dizziness, or collapse should prompt urgent assessment and likely a call to the emergency services.
